在此基础上

You usually place this phrase at the start of a second sentence or a new clause. First, you state the 'basis' or the current situation. Then, you drop 在此基础上 to signal the expansion. For example, 'We fixed the bugs. 在此基础上 (On this basis), we can now add new features.' It’s like saying 'With that being said' but much more constructive. You can use it in business reports, academic essays, or even just explaining your life goals to a friend. It works best when there is a clear logical link between the two parts. If you just finished your homework and then decided to go get bubble tea, you probably wouldn't use this unless the bubble tea was a direct reward for the homework. Use it when the second action is an upgrade or a logical next step. It’s the 'DLC' (Downloadable Content) of Chinese grammar.

This phrase sits comfortably in the 'neutral to formal' zone. You’ll hear it a lot in news broadcasts, business meetings, and university lectures. It makes you sound like a person who has a plan and thinks in organized steps. While it’s not too stiff for a serious chat with a friend about your career, you might not use it while shouting at a video game or ordering street food. It’s a bit like wearing a nice button-down shirt—it’s polished but not necessarily a tuxedo. If you use it in a casual text, you might sound slightly academic or 'professional,' which can be funny if used ironically. Most of the time, it’s used to show that you are being thorough. It’s the verbal equivalent of a PowerPoint slide transition that actually makes sense.

Think about a startup founder talking to investors on a Zoom call. They might say, 'We have 10,000 users. 在此基础上 (On this basis), we plan to double our revenue next year.' Or imagine a fitness influencer on TikTok explaining a workout. 'First, master the basic squat. 在此基础上 (On this basis), you can try jumping squats.' It’s everywhere in the tech world too. Software updates are almost always built 在此基础上 of previous versions. If you’re writing an email to a boss, it’s a great way to show you’re not just doing random tasks. It shows you’re building a cohesive strategy. Even in dating, you could say 'We have a great friendship. 在此基础上 (On this basis), let’s see if we can be more.' Though maybe save that for a particularly logical partner!

Use it when you want to sound organized and logical. It’s perfect for when you are presenting a plan or a series of steps. If you are writing an essay for the HSK test, this is a high-level transition that will impress the examiners. It’s also great for social media captions where you’re talking about your personal growth. Like, 'I learned to cook basic rice. 在此基础上 (On this basis), I am now a master of fried rice.' Use it when you want to emphasize that the first step was necessary for the second step to happen. It’s about continuity and building momentum. If you’re explaining why you deserve a promotion, this phrase is your best friend. It helps you link your past achievements to your future potential.

Don’t use it if there is no logical connection between your two points. If you say 'I ate a burger, and 在此基础上, I bought a new iPhone,' people will be very confused. There’s no 'basis' there, just a sequence of random events. Also, avoid it in extremely informal, slang-heavy settings where brevity is king. If you’re just texting 'u up?' to a friend, this phrase is way too heavy. It’s also not a replacement for simple 'and' or 'then.' If the second thing doesn't actually *build* on the first, don't use it. For instance, if you're listing items in a grocery store, just use 'and.' Don’t overcomplicate your shopping list unless you’re trying to write a philosophical treatise on eggs and milk.

A very common mistake is confusing it with 根据 (gēnjù), which means 'according to.' While they are related, 根据 points to a source of information, while 在此基础上 points to a foundation for growth. Another error is forgetting the 在 or the 上. It’s a fixed structure. Some learners also use it when the first part isn't actually a 'basis' but just a time marker.

Don't be the person who tries to sound smart but ends up sounding like a broken robot.

You might occasionally hear 在此基点上 (zài cǐ jīdiǎn shàng), which means 'on this base point,' but it’s much more technical and rare. A more common way to say something similar in casual speech is 在这个基础上 (zài zhège jīchǔ shàng). Adding the 个 makes it feel slightly more specific to the thing you just mentioned. In very formal writing, you might see 以此为基础 (yǐ cǐ wéi jīchǔ), which means 'taking this as the basis.' It’s the fancy suit version of our phrase. If you want to be even more concise, you could just say 在此之余 (zài cǐ zhī yú), meaning 'besides this,' but that changes the meaning to 'in addition to' rather than 'building on.' Stick to 在此基础上 for that solid 'building blocks' feeling. It's the classic choice for a reason.

Is it too formal for texting? Sometimes. Use it if you're discussing a project or a serious plan, but maybe not if you're just gossiping about a TV show.

Can I use it at the very start of a conversation? No. You need a 'basis' first! You must have mentioned something previously that acts as the foundation.

Does it mean the same as 'Therefore'? Not exactly. 'Therefore' is about result; 在此基础上 is about building and expansion.

How do I pronounce the 础? It’s third tone: chǔ. Make sure you don't confuse it with 出 (chū, first tone).

Is it okay for HSK exams? Yes, it's a great 'bridge' phrase for higher-level writing and speaking tasks.

Can I use it for physical objects? Absolutely. 'The workers laid the foundation. 在此基础上，they started building the walls.'
